SPIKED WASHER
A spiked washer is a specific type of washer used in orthopedic surgeries, particularly in conjunction with screws for bone fixation. Here's an overview of its specification and uses:
Specification
- Material: The abbreviation "TIT" indicates that the washer is made of titanium or a titanium alloy. Titanium is commonly used in medical implants due to its biocompatibility, strength, and resistance to corrosion.
- Spiked Design: The spiked washer features small protrusions or spikes on one side. These spikes help to grip the bone surface when the washer is placed, enhancing stability and preventing the screw from loosening over time.
- Size: The size of the washer can vary, typically corresponding to the size of the screw with which it is used. Common sizes include diameter and thickness specifications.
- Surface Texture: The surface of the washer may be textured to further enhance bone grip and stability.
Uses
- Orthopedic Surgery: Spiked washers are primarily used in orthopedic surgeries for bone fixation. They are often paired with screws to provide additional stability, especially in cases where the bone is osteoporotic or otherwise compromised.
- Fracture Repair: In the treatment of fractures, spiked washers may be used to secure screws in place, helping to hold fractured bone segments together during the healing process.
- Osteotomies: During procedures involving bone cuts or osteotomies, spiked washers can assist in maintaining alignment and stability at the surgical site.
- Bone Grafting: Spiked washers may also be utilized in bone grafting procedures to enhance the fixation of bone grafts or bone graft substitutes to the recipient bone.
- Revision Surgeries: In revision surgeries where previous implants have failed or need to be replaced, spiked washers can be used to improve fixation and stability of new implants.
Overall, spiked washers play a crucial role in enhancing the stability and longevity of orthopedic implants by providing additional grip and fixation to bone surfaces. They are designed to promote successful bone healing and improve patient outcomes in various orthopedic procedures.
